Although he's currently one of the favourites, Martin Scorsese really shouldn't win the Best Director Oscar for this. If he did, it would be as some sort of conciliatory reward for being ignored for Goodfellas, Raging Bull, Taxi Driver, etc. That's not to say this is a bad movie. It's a great crime thriller - solid, tight, well acted and exciting, just not all that remarkable. It does plenty of things right, particularly in the way it adapts the script of its Hong Kong original, Infernal Affairs. It stips the plot down to its skeleton, then re-fleshes it with free-wheeling character turns from Jack Nicholson, Leonardo DiCaprio, Matt Damon and Martin Sheen. The result is a shout compared to the slow, steady whisper of the original. The story is so simple and smart, it's a wonder it hasn't been flogged to death before. A cop goes undercover, joining a gang of criminals while a criminal rises through the ranks of the police force. Both know of the other's existence but not their identity. Both are so deep undercover that everything they do puts them at risk of fatal discovery. This two-disc version features plenty of deleted scenes - nothing major plotwise but plenty of extra character work and extra information - such as a quite incredible story of bullet ballistics. You also get a rundown of Scorsese's New York history, both personal and cinematic, as well as a documentary on real-life Bostonian crime lord Whitey Bulger, a man who makes Nicholson's wildly histrionic psychotic gangster seem almost subdued by comparison.

Style Wars£18.99, Weinerworld

"Is that an artform? I don't know, I'm not an art critic. But I can sure as hell tell you that that's a crime." These words come from an NYPD detective at the opening of this classic 1982 graffiti documentary, and they set the tone for what follows. It's an excellent record of the times, taking in the then-new breakdancing and hip hop scenes. For years, Style Wars has rightly been considered the last word on the subject, but this disc makes the whole thing even better. Not only do you get the movie with deleted scenes and commentary, but there's now an extra disc with archives and photos of over 200 whole subway trains covered with art. You also get 32 galleries from the artists involved, many with new interviews that show how this creative time affected their lives in many different ways. A great, soundtrack too, covering everything from the Sugarhill Gang to Wagner.
